I have an ’02 Chev 2500 with a manuel 4X4 shifter. My problem is 4hi won’t interact. 4lo seems to do the job just good, axle engages, lights within the dash appear on, I am able to hear front axle actuator engaging, but when I test 4hi practically nothing seems to happen.
You location these strings parallel to the sides of your automobile pulled taught and utilizing a small plumb bob and also a ruler or gauge board, measure the gap in the thrust line string where it exits the back of the vehicle to one facet outer string utilizing the plumb bob. Do not forget that length and transfer the ruler to your front, and do precisely the same detail, altering the front jack stand to try to get the space the exact same. Repeat right up until you happen to be contented that the two strings are parallel. Then repeat for another aspect of the vehicle. You'd like your outside the house strings being about nine inches absent from the wheel centers so you're able to transform your front wheels with out hitting the strings. Shown underneath is a pair of pictures displaying using a plumb-bob (and dial indicator holder) to insure the strings are parallel (click on for more substantial photos).
PS – nope, no other name with the Encoder Motor, that I know of. It’s Found about the side of the transfer scenario and it what does the physical shifting between “modes†(2Hi, 4Hi/4Lo).
Some how the program thinks the 4Lo button is getting pressed, Which’s what you should locate. Sadly, intermittent issues are the hardest to find.
Fantastic — I’m glad that my blog was ready to assist you to fix your trouble, and with any luck , conserve some money! Regards;
So, I've anything Doing work… time for the new glue. I put a dab of glue down the best of pins #one and #6 to carry them set up, Permit it set and attempted to pull them out.
You could potentially also unplug the TCCM and faucet within the encoder module to find out if it could be trapped (a heat garage wouldn’t harm possibly!) — leave the TCCM unplugged for at least 2 minutes, then plug it back in. Then, turn The important thing on to off five occasions, then to on and take a look at it.
In order to Check out a handful of items and get back to me with some additional facts/issues, I’d be content to try to enable you thru your trouble.
Hi Les — I’m about to have to say no as Raymond not has them — all over again, I apologize for not backing them up.
I don’t Believe this is probably going to become your challenge as you must likely listen to the encoder motor jogging (switching the drive mode from 2Hi to 4Hi/4Lo) — but there's a sensor about the hub to inform the TCCM when it is actually engaged, so it may be dilemma.
Something which you could Examine speedily is to lay down beside the car and have somebody Little by little drive forward (although in 4WD)… you’re planning to see If your driveshaft within the TC for the Look At These Guys front diff is definitely turning. Whether it is, the issue is ahead of that (ie. front diff), if not, the condition is within the TC.
Believed I would Provide you with an update on my 4wd problem. As I indicated in my authentic article, I'd a vaccum line unfastened. I thought it went into a canister inside the fender, what’s far more, I thought it had a little something to try and do with my 4wd not Functioning. Well, that was the case. I discovered the attachment for that line on the canister. I acquired a new vaccum line (the a person I'd was weathered), installed it and hooked it up on the canister. Then I went to a muddy area in the sub-division close to mine, drove into your mud in 2wd. I just sat the spinning the rear wheels. Then I pushed the 4HI button, the light flashed to get a second, then came on reliable.
I didn’t think nearly anything of it apart from that my floor heat was in all probability likely to blow in my face. The resolve that I performed from the parking lot on the nearby vehicle areas retailer took 5 minutes as well as the vacuum coupler tube only cost about 75 cents. Thanks once more for saving me a butt load of money!
The following factor I observed was that you choose to explained the lights around the sprint will flash once you push 4Hi — this tells you the button for 4Hi is working, plus the TCCM is accepting the sign from it. So, it boils down to a problem somewhere involving the TCCM as well as encoder motor — I'd personally suspect the TCCM — quite possibly wiring, or perhaps a nasty TCCM.
